✪ Regeneration Of The Seven Emperors →Used Deck

You can replenish materials while returning X, and depending on the situation, it can be an end card, but the requirements are heavy.
Burn is also slow and unstable, and since it's mutual, it becomes difficult to use depending on your own LP.
To be honest, for the weight and time it takes, I think it's a card.

Comprehensive evaluation: Can it be used for the return of CNo.101-107?
No. 101 to 107 seem necessary, but they are not particularly necessary for activation.
He could simply release the Xyz Monster and bring back his Xyz Monster that has been banished.
However, in that case, it would be necessary to find a way to remove his Xyz Monster, which was issued in a regular procedure.
If you do it normally, he will remove his Xyz Monster in GY and play "Gigantes" etc., Xyz Summon Dana.
Or does he Special Summon the monsters removed by 《Number C1: Numeron Chaos Gate Sunya》?
To be honest, I don't think there's much difference between this and Xyz Revenge Shuffle.
If No. 101-107 are in his GY or exclusion, they can be added to Xyz materials.
However, he should have released Xyz Monster, and it would be much easier to release the same monster as the one to return.
Therefore, Kana should aim to return C No. 101 to 107 and add the necessary monsters to the materials with that effect.
With 《Rank-Up-Magic - The Seventh One》, the corresponding monster can be Xyz Summoned, and if it's removed, it's null for follow-up.
The burn of the number of cards in hand is slow in the end phase, and it's better than nothing.
